Stop being so straight-forward, guys and gals.
"Psychologists have been interested in the idea of improving intelligence for over a century."
And yet, only in 2008 we had some research that BARELY scratched the surface. Now it's already proven to be wrong. That does not mean, however, that brain training games don't work. We need more studies about that. I concur with the guy who commented that learning a musical instrument, a language or dance or anything that will require a huge concentration and mind effort will be probably better than a brain-game. The thing is that those activities requires so much time, and in this busy society we live in, for some it's just not possible to commit time to those.
I can see the attractive those brain games have. They don't take much of your time. Only 20 minutes per day and you will get good results eventually, just like the gym (people usually train for 40 minutes to 1 hour).
I guess we need to wait for more research on this are, and just stop jumping to conclusions. Or we can become scientists and help =D
